Oooph, that is a tough choice. Both are very, very nice basses, and would both work very well for what you are playing.

My vote goes to the Q5, I guess. Mainly because when I was shopping, it was narrowed down to a new Q5 or a new NS5CRFM. The Q5 was considerably more expensive, but there is just something about the Modulus sound that really gets me going. Mine has Bart pups and NTMB (3 band) Bart EQ.

I am still gassing for a Czech Spector though, too.

You are just gonna have to spend some time on each of them (if at all possible) and see which one feels and sounds the best to you.

Are you looking at a graphite neck on the q5? I would agree that either seems like a win/win situation IMO...i guess it would boil down to trying them both out and just going "hey, this one does it for me..." either way, you are purchasing a great bass.

All I know, is If I were in your position, I would be a very happy, content, and calm person

Enjoy...either decision is a good one. Personally, I like the sound of modulus basses a bit more (especially graphite necked modulus basses...), but again...either decision=victory

Well, I don't really like Czech Spectors (working on selling mine), and I haven't tried any Moduli except for a Quantum Sweetspot with an EMG which I absolutely hated... However, I've heard insanely good things about Quantums with Bartolini pickups, so I'd probably go that route.
